Description
Technical field
The present invention relates to chemical material technical fields, in particular to a kind of cable cover(ing) with self-repair function
Material, preparation method and cable cover(ing).
Background technology
Cable, often because insulating layer aging leads to electric leakage even power-off fault, causes huge economic losses and peace in operational process
Full hidden danger.The cable fault proportion caused by insulating layer Aging Damage etc. is maximum in cable fault.China's electric wire is used
Insulating materials mainly has polyvinyl chloride (PVC), polyethylene (PP), polypropylene (PP) and crosslinked polyethylene (XLPE).These materials
The Common advantages of material are excellent electric properties, good insulation preformance；But common disadvantage is：As traditional polymer material, this
A little materials do not have intelligent.Even if slight Aging Damage will also result in the deterioration of material property.And it pushes away at any time
It moves, Small loss can be aggravated constantly, finally result in the thorough forfeiture of material mechanical performance or insulation performance.Currently, to existing cable
The repairing of insulating materials is repaired mainly by repairing the filling reparation of liquid, hot weld reparation and heat-shrink tube reparation.
Repair the filling reparation of liquid has preferable repairing effect to water tree class defect, XLPE classes easily occurs the electricity of water-treeing
Cable, can effective extender service life.But the technical process used that cable repairs liquid is cumbersome, needs to note accordingly
Enter equipment and cable accessory, job execution is complicated；Cable repairs liquid only has repairing effect to aqueous defect, to other erosions
Class defect cannot generate any reparation.Hot weld reparation is that occur damaging, scratch, weigh wounded or puncturing the defects of point in cable insulation
When, PVC analog thermoplastics insulating layer can be bonded material part melting using hot weld after defect area inserts homogeneous plastic
Repairing, it is then wrapped with carrying out with repairing in mend.But this method is not suitable for XPLE etc. and has generated crosslinked material
Material.Also, hot weld repairing need to use electric iron or hot air welding gun for tool, and technique is also relative complex, it is desirable that operating personnel have
Higher technical merit.In addition, for the smaller core in section, it is not easy to ensure quality.Heat-shrink tube reparation is that size is suitable
Shrinkable sleeve makes casing shrink to hard-pressed bale defect in defect area, heating.This method and process is relatively simple, and applicable range also compares
It is relatively wide.But after being repaired using heat-shrink tube, cable insulation layer thickness increases, and heat dissipation difficulty is made to increase, and is easy to cause connector hair
Heat, and further generate failure.
Currently, external be concentrated mainly on the research of cable reparation in the developmental research that novel cable repairs liquid.For example, beautiful
Utilx companies of state and Europe Novinium companies mainly apply silane to repair the water tree in liquid repairing XLPE cable, repairing effect
Preferably.But the filling process that cable repairs liquid is very complicated, needs corresponding injection device and cable accessory, and silane
Repair liquid only has repairing effect to water tree class defect, and any reparation cannot be generated to other erosion class defects.
The Sergio in the U.S. et al. is reported a kind of " cable with selfreparing protective layer ".This cable is in cable insulation
It is filled with a kind of flowable, with repairing performance semifluid between layer and restrictive coating, when cable cover(ing) or insulating layer damage
When, the liquid of repair layer penetrates into crack realization and fills up and repair.But this be additionally added in multilayer cable structure repairs liquid layer
Method do not obtain practical application at present, reason is mainly that the technology difficulty that produces is big, is difficult to carry out.

Degree.Also, this physical crosslinking point of cyclodextrin-adamantane can the reversible progress repeatedly under conditions of as mild as a dove, then exist
When material meets with aging equivalent damage, although cyclodextrin-adamantane crosslinking points in system are destroyed and pull open, but damage section part trip
From cyclodextrin under normal temperature environment can tend to recombine with adamantane group, regenerate crosslinking points, the weight of crosslinking points
It is newly-generated so that obtaining self-healing at material damage.This reparation can be carried out repeatedly, also, be stimulated without external condition.Again
By adding the auxiliary agents such as plasticizer, reinforcing agent and stabilizer, the mechanical property and electric property of material ensure that.In addition, this hair
The preparation method step of bright offer is simple, easily operated, and additional prosthetic appliance is not needed when repair materials damage, and repaiies
It is multiple simple for process, be conducive to large-scale promotion.
The third aspect, the present invention propose a kind of cable cover(ing), by the above-mentioned cable cover(ing) material with self-repair function
Material is made.Since cable sheath material has above-mentioned technique effect, the cable cover(ing) made of the material also has accordingly
Technique effect.
Fourth aspect, the invention also provides a kind of cables, are coated cable core by above-mentioned cable cover(ing) and are made.Due to electricity
Cable, often because insulating layer aging leads to electric leakage even power-off fault, causes huge economic losses and security risk in operational process.Electricity
The cable fault proportion caused by insulating layer Aging Damage etc. is maximum in cable accident.China's electric wire is with sheath material master
There are polyvinyl chloride, polyethylene, polypropylene and crosslinked polyethylene.The common disadvantage of these materials is：Gather as traditional
Object material is closed, these materials do not have intelligent, even if slight Aging Damage, will also result in the deterioration of material property.And
And over time, Small loss can be aggravated constantly, finally result in the thorough forfeiture of material mechanical performance or insulation performance.Passing through will
Cable sheath material provided by the invention with self-repair function is prepared into cable cover(ing), microcosmic scarce when occurring in cable cover(ing)
When falling into, material can carry out multiple selfreparing, so as to effectively extend the service life of cable.
